SPECIFICATION forming part of Letters Patent No. 540,286, dated June 4;,1895. Application filed October 29. 1894. $erial Not 527,306. (Nomodel.)

To all whom it may concern.-

Be it known that I, FRED WAITE, a subject. of the Queen of England,residing at Otley, England, have invented certain new and usefulImprovements in Printers Quoins, of

which the following is a specification.

This invention relates to improvements in printers quoins, and itsobject is to provide a simple and readily adjustable quoin without looseparts and free from any liability to slip or shake loose. For thispurpose I employ a guide piece having parallel guides between or uponwhich guides a sliding or adjustable block is fitted. This sliding blockis adjusted within the said guidesto expand or contract the quoin-bymeans of a screw fitting a female screw thread cut in the block. To keepthe sliding block in position in the guide piece the head of the screwoperating the sliding block may lie in a recess in the said guide pieceand be so arranged that while it is perfectly free to be rotated, toturn the screw, it is prevented from longitudinal movement in relationto the guide piece.

Reference is to be had to the accompanying sheet of drawings, forming apart of this specification, in which similar letters of referenceindicate corresponding parts in each of the figures.

Figure '1 represents a plan view of my improved quoin. Fig. 2 representsa side view, and Fig. an end view, of the same. Fig. at represents asectional view on the broken line a b, Fig. 1. Figs. 5 and 6respectively represent a separate plan view of the guidepiece and thesliding block.

.The guide pieceAis provided with parallel guides B, B between which thesliding block 0 is fitted. Said piece A has the transverse portions A, AThe screw D fits the female screw thread cut in the hole E through theblock 0 and its head F lies in the opening or recess G formed in theguide piece A between the transverse portions A A and the screw isthereby confined longitudinally. Holes H are drilled through the head ofthe screw to admit the end of a lever to tighten "up the screw when thequoin is in position.

The under side of the sliding piece is preferably a little above theunder side of the guide piece so as to allow it to slide freely in orout when in position; and to maintain the sliding block in this positionin relation to the guide piece the sliding block is provided withlateral lips J, J arranged to rest upon the top of the guides B, B.

I claim 1. In a printers quoin, the combination with the guide piece Aprovided with parallel guides B, B, of the sliding block G fitted andadapted to-slide between said guides, the bottom of the block beingabove the bottom of the guide piece, for the purpose specified.

2. In a printers quoin, the combination with the guide piece A providedwith parallel guides B, B, of the sliding block 0 fitted and adapted toslide between said guides, the bottom of the block being above thebottom of the guide piece, and the lateral lips J, .l, on the block 0resting upon the upper face of the guides, as and for the purposespecified.

3. In a printers quoin, the combinationwith the guide piece A providedwith parallel guides B, B, the transverse portions A A on said guidepiece, the latter having an opening G between said portions, the slidingblockfil fitted and adapted to slide between said guides and having athreaded opening, and the portion Abeing provided with an opening and aheaded screw working in. the opening in block 0 and passing through theopening inthe portion A and the head of the screw lying within theopening G between the portions A A of the guide piece, as and for thepurpose specified.

In witness whereof I have hereunto set my hand in the presence of thetwo subscribing witnesses.

FRED VVAITE.
